Specifications - Optex TC-Mi Instruction Manual

Periodic inspection
■Inspect the following items every month:
•Scratches on the cable or cable deterioration
•Water leakage from the water inlet, water outlet, or drain
•Check if the unit outputs a correct value when the measurement water with known
concentration is used.
•If the cover or display area is contaminated, clean it by using a clean soft cloth.
■Inspect the following items every 3 months:
•Ensure that TC-Mi is fixed securely.
•Ensure that TC-Mi is not damaged.
•Make sure that the screws of the Terminal Block are not rusted.
Storage for a long time
■When the Turbidity Checker TC-Mi is not used over a prolonged period, keep it as
follows:
•Drain off the water from the measurement tank and keep the water. Follow the
procedure below.
(1) Stop feeding water to this product.
(2) Detach the drain cap and let the water come out of the tank, and protect the water outlet.
(3) Wash the drain cap and keep it in a clean place.
(4) Disconnect the tube at the water inlet (In order to protect the inflow port, keep the joint attached.).
Pull out the tube as pushing
the end of the joint in.
(5) The tube does not have to be disconnected from the water outlet.
(6) Open the panel and shut down the power supply switch.
(7) Disconnect the power cable from the power source and attach the
•Keep TC-Mi at a place not being exposed to direct sunshine.
Caution
•Leaving the drain cap in place allows rain to come into the measurement tank.
The drain cap must be detach and kept.
•Be careful not to damage the water inlet and outlet. Damage causes water
leakage and could result in malfunction, which requires replacement of the unit.
